From the big house in Calabasas, Miz Spears moved on to an even bigger mansion on 3-plus acres estate in the guard-gated Hidden Hills community.

Outside the, expansive, high maintenance and fully-landscaped estate offers a private pond, sunken tennis court, and dark-bottomed lagoon style swimming pool with Playboy Mansion-esque spa grotto.
